kubernetes: Log in to dashboard as admin

I have deployed a k8s cluster to aws using kops.

The process created a ~./kube/config file with the following structure:

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: 
      <data_here>
  name: <cluster_name>
contexts:
- context:
    cluster: <cluster_name>
    user: <cluster_name>
  name: <cluster_name>l
current-context: <cluster_name>
kind: Config
preferences: {}
users:
- name: <cluster_name>
  user:
    as-user-extra: {}
    client-certificate-data:
    <client_certificate_data>
    client-key-data: 
    <client-key-data>
    password: <some-password>
    username: admin
- name:<cluster-name>-basic-auth
  user:
    as-user-extra: {}
    password: <some-password>
    username: admin

When (after creating the dashboard) I perform kube proxy and try to access it via localhost, I am prompted with the following screen:

enter image description here

1: Why when I point the file browser to the above created ~./kube/config file I get

Authentication failed

2: When I provide the password included in the ~./kube/config file, I do log in but not as an administrator (e.g. I am unable to view compute resources on the pods)

You can give the admin access by running this yaml file : 

kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  name: dashboard
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: kubernetes-dashboard
  namespace: kube-system

This will allow access to the kubernetes dashboard. But this will give open access, you need to do skip the login after running this. more details can be found here https://github.com/kubernetes/dashboard/wiki/Access-control
